Hi,
Been scratching my head on this one for a few days.
I've just replaced all the rads in my house bar a few which I'll do later this week.
System fully bled and it's running on an Intergas Rapid 32.
What I cannot get my head around is this:-
1) I was looking for some cheap rad thermometers but it's a case of you get what you pay for with some buyers on Amazon claiming they are like 20degC out!!! The guy in the Drayton TRV4 video uses a Jet thermometers but they are £80 a piece! No way I want to pay that.
Anyhow, I have a Draper Laser Thermometer so I think I'll have to make do with that on the bottom channel of either side of each rad as I reckon that's probably more accurate than trying to get an accurate reading off the pipes.
2) It seems I've fitted some TRV4's on the return side. Do I need to change these to the correct side?
I'm thinking not as they are listed as bi-drectional and I saw over the weekend that you can buy a Drayton TRV4 balancing key? But I'm thinking, "OK. So I can adjust the flow on the TRV side even if it is on the return pipe but that it might affect the accurate operation of the TRV itself?
Still got loads of floorboards up so I could go around and map out which pipe goes where to gain a better understanding of what goes where exactly or is this not really umportant?
I know which radiators heat up first.
Thanks in advance.
